本考案は、連結ピンを挿通するチェーンブシュおよび回動軸を挿通するローラ 軸孔等の内周面に嵌装した樹脂製スリーブの遊動防止装置に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating prevention device for a resin sleeve fitted on the inner peripheral surface of a chain bush through which a connecting pin is inserted and a roller shaft hole through which a rotary shaft is inserted.
【０００２】[0002]
回動軸の挿通孔内周面には回動軸との摺動摩損を防止するとともに回動抵抗を 軽減するために潤滑性にすぐれた樹脂製スリーブを嵌装することが従来より実施 されている。 そして特願平４−１０３９０５号の明細書並びに図面に開示するように射出成 形によって回動軸挿通孔内周面に樹脂製スリーブを形成する方法も開発されてい る。 It has been practiced in the past to fit a resin sleeve with excellent lubricity on the inner peripheral surface of the insertion hole of the rotating shaft in order to prevent sliding friction with the rotating shaft and reduce the rotating resistance. There is. As disclosed in the specification of Japanese Patent Application No. 4-103905 and the drawings, a method of forming a resin sleeve on the inner peripheral surface of the rotary shaft insertion hole by injection molding has been developed.
【０００３】[0003]
上述した従来技術においては、回動軸挿通孔内周面と樹脂製スリーブ外周面と は密嵌力で相対的な軸方向並びに周方向の移動が拘束されているが、密嵌による 拘束力は弱いために使用中に相対的な移動が発生し、樹脂製スリーブに遊動によ る摩損が生じ、該スリーブの耐用寿命を著しく低下させる欠点を有していた。 In the above-mentioned conventional technology, the inner peripheral surface of the rotary shaft insertion hole and the outer peripheral surface of the resin sleeve are constrained from relative movement in the axial and circumferential directions by a tight fitting force. Due to its weakness, relative movement occurs during use, and the resin sleeve suffers wear due to looseness, which has the drawback of significantly reducing the useful life of the sleeve.
【０００４】[0004]
そこで、本考案は上述した従来技術の欠点を解決するために、該スリーブ両端 に非円形、偏心円形又は内側面に係止凹凸を有する遊動防止フランジ部を一体形 成し、該フランジ部が嵌合係止する凹部を回動挿通孔を貫設した部材の側面に形 成したものである。 Therefore, in order to solve the above-mentioned drawbacks of the prior art, the present invention integrally forms a non-circular, eccentric circular or anti-floating flange portion having locking irregularities on the inner side at both ends of the sleeve, and the flange portions are fitted. The concave portion for engaging and locking is formed on the side surface of the member having the rotary insertion hole formed therethrough.
【０００５】[0005]
樹脂製スリーブ両端に遊動防止フランジ部を形成したので、該スリーブの軸方 向遊動は拘束され、また、フランジ部の遊動防止形状を非円形、偏心円形又は内 側面に係止凹凸を有する円形として、回動軸挿通孔を貫設した部材側面に凹設し た前記フランジ形状と同形の嵌着凹部に嵌合係止することによって、該スリーブ の周方向遊動は拘束される。 Since the anti-floating flanges are formed at both ends of the resin sleeve, the axial free movement of the sleeve is restricted, and the anti-floating shape of the flange is made non-circular, eccentric circular, or circular with locking irregularities on the inner side. By fitting and locking in a fitting recess having the same shape as the flange shape, which is recessed in the side surface of the member penetrating the rotary shaft insertion hole, the circumferential free movement of the sleeve is restricted.

図１は、チェーンの内リンクプレートＬに圧嵌した連結ピン挿通ブシュ１の内 周面に射出成形によって嵌装形成した方形フランジ部２を両端に有する樹脂製ス リーブ３であって、（Ａ）は断面図、（Ｂ）は平面図であり、挿通孔貫設部材で ある内リンクプレートＬの外側面には方形フランジ部２が嵌合する方形の凹部４ が凹設されているから、該スリーブ３は方形フランジ部２によってブシュ１に対 して軸方向並びに周方向の相対的遊動を拘束される。 なお、ブシュ１にはローラＲが回動自在に外嵌されている。 FIG. 1 shows a resin sleeve 3 having square flange portions 2 at both ends, which are formed by injection molding on the inner peripheral surface of a connecting pin insertion bush 1 press-fitted to an inner link plate L of a chain. ) Is a cross-sectional view, and (B) is a plan view. Since a square concave portion 4 into which the square flange portion 2 fits is formed on the outer surface of the inner link plate L that is the insertion hole penetrating member, The sleeve 3 is constrained by the rectangular flange portion 2 from moving relative to the bush 1 in the axial and circumferential directions. A roller R is rotatably fitted on the bush 1.
【０００７】 図２は、樹脂製スリーブ３のフランジ部２Ａが長円形状を有し、内リンクプレ ートＬの外側面に凹設した長円形凹部４Ａに嵌合し、（Ａ）は断面図、（Ｂ）は 平面図である。In FIG. 2, the flange portion 2A of the resin sleeve 3 has an oval shape, and is fitted into an oval recess 4A provided on the outer surface of the inner link plate L. Figure (B) is a plan view.
【０００８】 図３は、樹脂製スリーブ３のフランジ部２Ｂが円形であって該フランジ内側面 には廻り止め突起２’が形成され、該突起２’は内リンクプレートＬの外側面に 形成した円形凹部４Ｂの底面に凹設した穴４’に嵌入係合してスリーブ３の周方 向回動を拘束する。In FIG. 3, the flange portion 2B of the resin sleeve 3 has a circular shape, and a whirl-stop projection 2'is formed on the inner surface of the flange, and the projection 2'is formed on the outer surface of the inner link plate L. The circular recess 4B is fitted into a hole 4'provided on the bottom surface of the recess 4B to restrain the sleeve 3 from rotating in the circumferential direction.
【０００９】 図４は、ローラＲの支持軸挿通孔内周面に嵌装した樹脂製スリーブ５の両端部 に方形フランジ部６を形成し、ローラＲの側面には、前記方形フランジ部６が嵌 入する方形凹部７が形成された他の実施例であって、フランジ部６の形状は方形 に限らず、図１〜３に図示した如く非円形、偏心円形又は内側面を凹凸形状にし ても差し支えない。In FIG. 4, rectangular flange portions 6 are formed at both ends of a resin sleeve 5 fitted to the inner peripheral surface of the support shaft insertion hole of the roller R, and the rectangular flange portion 6 is formed on the side surface of the roller R. It is another embodiment in which a square recess 7 for fitting is formed, and the shape of the flange 6 is not limited to a square, but as shown in FIGS. It doesn't matter.

【考案の効果】 本考案は、樹脂製スリーブの両端部に廻り止めフランジ部を形成し、該フラン ジ部をブシュ、ローラ等の回動軸挿通孔貫設部材外側面に形成した該フランジ部 と同形の凹部に嵌合係止したので、回動軸挿通孔内周面と樹脂製スリーブ外周面 との嵌装面において軸方向並びに周方向の相対的移動が全く拘束されるので遊動 が防止され、樹脂製スリーブの遊動に起因する摩損がなくなり、耐用寿命が延び 、また、軸方向の遊動が拘束されたことにより該スリーブの飛び出し欠損或いは 脱落等の事故が防止され、しかもチェーンブシュの場合は、内リンクプレート外 側面に樹脂製フランジ面が露出しているので、外リンクプレート内側面との摺接 によるスラスト音が低下し、さらに、フランジ部を有する樹脂製スリーブは射出 成形によって簡単に回動軸挿通孔内周面に嵌装することができるので、スリーブ の圧入嵌装又はスリーブの軸方向遊動を阻止するためにスリーブ両端に圧入する 止め輪加工等の面倒な工程を省略できる等、その実用的効果は著大である。EFFECTS OF THE INVENTION The present invention has a flange portion formed on both ends of a resin sleeve, and the flange portion formed on the outer surface of a rotary shaft insertion hole penetrating member such as a bush or a roller. Since it is fitted and locked in a recess of the same shape, relative movement in the axial and circumferential directions is completely restrained on the fitting surface between the inner peripheral surface of the rotary shaft insertion hole and the outer peripheral surface of the resin sleeve, preventing loose movement. Therefore, the wear caused by the looseness of the resin sleeve is eliminated, the service life is extended, and the axial looseness is restrained to prevent the sleeve from popping out or falling off. , The resin flange surface is exposed on the outer side of the inner link plate, so the thrust noise due to the sliding contact with the inner side of the outer link plate is reduced. Since it can be easily fitted to the inner peripheral surface of the rotary shaft insertion hole by molding, it is a troublesome process such as press fitting of the sleeve or press fitting to both ends of the sleeve to prevent axial free movement of the sleeve. Can be omitted, and its practical effects are remarkable.
